Elladarian: Custom Set Challenge

If you go to my profile and check on my sets, you'll notice one called "Elladarian," featuring 60 cards, making it my biggest set. But I stopped working on it nearly two years ago. Now it's finally time to have it finished, but not by me, so I thought I'd turn it into a fun challenge.

This got way too long, so please read the detailing of the rest attached in the .pdf.
